CXP84716/84720/84724
CMOS 8-bit Single Chip Microcomputer
Description
The CXP84716/84720/84724 is a CMOS 8-bit micro-
computer integrating on a single chip an A/D converter,
serial interface, timer/counter, time base timer, capture
timer/counter, FRC capture unit, high-precision timing
pattern generation circuit, PWM output, and the like
besides the basic configurations of 8-bit CPU, ROM,
RAM, and I/O port.
The CXP84716/84720/84724 also provides the
sleep/stop functions that enable to execute the power-
on reset function and lower the power consumption.
